The diagnosis unit 102 receives the supercharger state quantity acquired by the supercharger state quantity acquisition unit 101 and information from the engine controller 301, and based on the input supercharger state quantity and information from the engine controller 301. The deterioration state of the hybrid supercharger 20 is diagnosed.

The hybrid supercharger 20 includes a turbine 201, a compressor 202, and a motor generator 203.
The turbine 201 sucks exhaust gas discharged from the engine 30. The turbine 201 is rotated by the exhausted exhaust gas.
The compressor 202 rotates the compressor wheel provided in itself by the rotational force of the turbine 201 via the shaft. The compressor 202 compresses air by rotating a compressor wheel. Then, the compressor 202 sends scavenging, which is compressed air, to the engine 30.
The motor generator 203 generates electric power by surplus rotational force out of the rotational force of the turbine 201 via the shaft. The motor generator 203 transmits the generated power to the power converter 10.

The engine 30 draws scavenged air from the compressor 202 and exhausts exhaust gas to the turbine 201. The engine 30 includes an engine controller 301.
The engine controller 301 acquires scavenging and exhaust gas information of the engine 30. The engine controller 301 transmits and receives information to and from the inboard control device 40 and the control device 100.

The inboard control device 40 transmits / receives information to / from other controllers 50, the control device 100, and the engine controller 301. Further, the inboard control device 40 transmits / receives information to / from an external device of the ship system 1.

Moreover, it is a memory | storage part which memorize | stores the information which each of the inboard control apparatus 40, the other controller 50, and the engine controller 301 acquired.

FIG. 2 is a diagram illustrating an example of processing in which the diagnosis unit 102 according to the first embodiment diagnoses the deterioration state of each device.
The measured values shown in FIG. 2 are measured values of various physical quantities in the hybrid turbocharger 20 received by the diagnosis unit 102 from the supercharger state quantity acquisition unit 101. The measured values shown in FIG. 2 are measured values of various physical quantities in the engine 30 acquired from the engine controller 301.
The average value processing, FFT (Fast Fourier Transform) processing, and comparison processing with threshold values shown in FIG. 2 are performed by the diagnosis unit 102. Each component of each device, for example, mechanical parts such as wings, housings, bearings, etc. , Calculation of remaining lifetimes of electrolytic capacitors, batteries, IGBTs (Insulated Gate Bipolar Transistors), reactors, generator coils, and the like as electrical products, and determination processing for determining whether or not each device causes trouble.
Further, the diagnosis result of the apparatus shown in FIG. 2 is a determination result obtained when the diagnosis unit 102 determines whether each apparatus does not cause a trouble. In addition, each apparatus in embodiment is one or more of the turbine 201, the compressor 202, and the motor generator 203.

By the way, each of the devices such as the turbine 201, the compressor 202, and the motor generator 203 included in the hybrid supercharger 20 and the components of each device deteriorate at the design stage and how long the operation state continues for how long. (How much the lifespan will be shortened).
Thus, for example, when the turbine 201 is operated at a temperature of 400 degrees and a rotational speed of 10,000 revolutions / minute, the part a in the turbine 201 reaches the end of life in 5 years, and the part b in the turbine 201 reaches the end of life in 3 years. This can be understood at the design stage. For example, when the turbine 201 is operated at a temperature of 600 degrees and a rotational speed of 8000 rpm, the part a in the turbine 201 reaches the end of its life in 3 years, and the part b of the turbine 201 reaches the end of its life in 5 years. This can be understood at the design stage. This means that the deterioration of each component can be calculated by accumulating the operation status in the time axis direction, and the remaining life of each component can be calculated.

  Therefore, the diagnosis unit 102 calculates the remaining life of each part based on the operating state, and when the calculated life is shorter than the predetermined life, replacement of the part or maintenance of the apparatus using the part By prompting, troubles in each device can be prevented in advance.

  In addition, the diagnosis unit 102 calculates an average value for various physical quantities in each component based on the operation status received from the supercharger state quantity acquisition unit 101. The diagnosis unit 102 then determines the remaining life of the component when the average value for the calculated various physical quantities exceeds the preset upper limit threshold for the various physical quantities or falls below the lower limit threshold. Is determined to be short. Then, the diagnosis unit 102 can prevent troubles in each device by exchanging the component and urging maintenance of the device using the component.

  In addition, each part of each device has a different material, shape, etc., and a different natural frequency. Therefore, for example, when calculating the deterioration of each component using vibration, the diagnosis unit 102 needs to extract only the frequency that affects the deterioration and reflect it in the calculation. In such a case, the diagnosis unit 102 performs an FFT operation on the frequency in each device, and extracts a frequency component related to the deterioration of each component from each frequency component obtained by the operation. Then, the diagnosis unit 102 reflects only the time when the vibration of the frequency component related to the deterioration of each component has occurred in the calculation of the deterioration.

FIG. 3 is a diagram illustrating an example of information flow in the ship system 1 including the control device 100 according to the first embodiment.
Moreover, FIG. 4 is a figure which shows an example of the processing flow of the ship system 1 provided with the control apparatus 100 by 1st embodiment.
Next, the processing flow (step S1-step S8) of the ship system 1 provided with the control apparatus 100 by 1st embodiment is demonstrated using FIG. 3 and FIG.
It is assumed that the hybrid supercharger 20 and the engine 30 are operating together. Further, in the hybrid supercharger 20 and the engine 30, various physical quantities such as pressure, flow rate, temperature, vibration, stress, operation time, rotation speed, electric power, etc. are measured using a sensor or a measuring instrument. And

  The supercharger state quantity acquisition unit 101 acquires measurement values of various physical quantities in each of the turbine 201, the compressor 202, and the motor generator 203 included in the hybrid supercharger 20 and the respective bearings (step S1). The supercharger state quantity acquisition unit 101 transmits the acquired measured values of various physical quantities to the diagnosis unit 102 (step S2). The supercharger state quantity acquisition unit 101 records the acquired measured values of various physical quantities in the storage unit 60.

  The diagnosis unit 102 receives measurement values of various physical quantities in the hybrid supercharger 20 from the supercharger state quantity acquisition unit 101 (step S3). Further, the diagnosis unit 102 acquires measurement values of various physical quantities in the engine 30 from the engine controller 301 that controls the engine 30 (step S4). Then, the diagnosis unit 102 is based on the measured values of various physical quantities in the hybrid turbocharger 20 received from the supercharger state quantity acquiring unit 101 and the measured values of various physical quantities in the engine 30 acquired from the engine controller 301. Then, the deterioration of each of the turbine 201, the compressor 202, and the motor generator 203 is calculated, and it is determined whether or not the remaining life of each component is sufficient (step S5).

For example, the storage unit 60 stores a deterioration degree data table that indicates the operation status and how long the operation status continues for each component of each device (how much the life is shortened). Yes. In addition, the storage unit 60 stores in advance a threshold value that is shorter than the lifetime of each component in each device determined at the design stage.
The supercharger state quantity acquisition unit 101 sequentially acquires the operation statuses of each of the turbine 201, the compressor 202, and the motor generator 203 included in the hybrid supercharger 20, that is, the measurement values of various physical quantities, and acquires the various physical quantities acquired. The measured value is transmitted to the diagnosis unit 102. Further, the supercharger state quantity acquisition unit 101 records the acquired measured values of various physical quantities in the storage unit 60.
The diagnosis unit 102 receives measurement values of various physical quantities from the supercharger state quantity acquisition unit 101. In addition, the diagnosis unit 102 reads out the deterioration degree data table from the storage unit 60 and a threshold value shorter than the lifetime of each component in each device determined in the design stage. Based on the deterioration degree data table read from the storage unit 60 and the operation status received from the supercharger state quantity acquisition unit 101, the diagnosis unit 102 determines each component in the turbine 201, the compressor 202, and the motor generator 203. Calculate degradation and calculate remaining life. The diagnosis unit 102 compares the calculated remaining lifetime of each component with the lifetime of each component in each device determined at the design stage read from the storage unit 60, and there is sufficient remaining lifetime for each component. Is determined (step S5).
The diagnosis unit 102 determines that the calculated remaining lifetime of each component is longer than the lifetime of each component in each device determined at the design stage read from the storage unit 60, that is, the remaining lifetime of each component is sufficient. When it does (step S5, NO), the supercharger state quantity acquisition unit 101 returns to the process of step S1 in which the measurement values of various physical quantities in each of the turbine 201, the compressor 202, and the motor generator 203 and the respective bearings are acquired. .
Further, the calculated remaining lifetime of each component is shorter or the same as the lifetime of each component in each device determined at the design stage read from the storage unit 60, that is, the remaining lifetime of each component is not sufficient. If the diagnosis unit 102 determines (YES in step S5), information on the component determined to have an insufficient remaining life and the device using the component is transmitted to the inboard control device 40 (step S6).

Further, the diagnosis unit 102 calculates an average value of past physical quantities indicating the driving situation received from the supercharger state quantity acquisition unit 101. Then, the diagnosis unit 102 compares the calculated average value of the physical quantities with the upper limit threshold value indicating the upper limit and the lower limit threshold value indicating the lower limit set in advance for each physical quantity, and determines the remaining life of each component. It is determined whether there is enough (step S5).
When the diagnosis unit 102 determines that the calculated average value of the physical quantities does not exceed the upper limit threshold set in advance for each physical quantity and does not fall below the lower limit threshold, the diagnosis unit 102 indicates that the component has deteriorated. In other words, it is determined that the remaining life of each component is sufficient (step S5, NO), and the supercharger state quantity acquisition unit 101 performs various operations in each of the turbine 201, the compressor 202, and the motor generator 203 and the respective bearings. The process returns to the process of step S1 for acquiring the measured value of the physical quantity.
In addition, when the diagnosis unit 102 determines that the average value of the calculated physical quantities exceeds a preset upper limit threshold or falls below a lower limit threshold for each physical quantity, the diagnosis unit 102 It is determined that the remaining life of the component is not sufficient, that is, the remaining life of the component is not sufficient (step S5, YES), and information on the component and the device using the component determined that the remaining life is not sufficient It transmits to the control apparatus 40 (step S6).

  In addition, each part of each apparatus differs in a material, a shape, etc., and a natural frequency differs. Therefore, when the diagnosis unit 102 calculates the deterioration of each component using, for example, vibration, it is necessary to extract only the frequency that affects the deterioration and reflect it in the calculation of the deterioration. In such a case, the diagnosis unit 102 performs FFT on the frequency indicating the operation status in each device, and extracts the frequency related to the deterioration for each component. Then, the diagnosis unit 102 reflects only the time with the frequency extracted for each component in the calculation of deterioration.

When the diagnosis unit 102 transmits to the inboard control device 40 information regarding the component determined by the diagnosis unit 102 that the remaining life is not sufficient by the process of step S6 and the device using the component, the inboard control device 40 receives the information. (Step S7). Then, the inboard control device 40 arranges parts with the manufacturer, schedules maintenance, etc. based on the information received from the diagnosis unit 102 and determined that the remaining life is not sufficient and the device using the parts. (Step S8).
When it is difficult for the supercharger state quantity acquisition unit 101 to acquire various physical quantities from the hybrid supercharger 20, the diagnosis unit 102 estimates the physical quantity of the hybrid supercharger 20 based on the engine load state. May be. The diagnosis unit 102 acquires the engine load state by reading out information on the engine load state acquired by the engine controller 301 and recorded in the storage unit 60 or information on the engine load state recorded in the storage unit 60 by the inboard control device 40. be able to.
Further, in the process of step S5, the diagnosis unit 102 determines whether deterioration with time has occurred by continuously monitoring past physical quantities, and based on the determination result, the remaining part of each component is determined. It may be determined whether the lifetime is sufficient.

  The information signal transmitted / received between the devices may be an analog signal, a digital signal, or a combination thereof within a range in which information can be correctly transmitted and recognized by each device. Further, the communication method may be any communication method or a combination of a plurality of communication methods as long as information is correctly transmitted and recognized by each device.

<Second Embodiment>
FIG. 5 is a diagram illustrating an example of a configuration of the ship system 1 including the control device 100 according to the second embodiment of the present invention.
Next, the ship system 1 provided with the control apparatus 100 by 2nd embodiment is demonstrated.
As shown in FIG. 5, similarly to the ship system 1 according to the first embodiment, the ship system 1 according to the second embodiment includes a power converter 10, a hybrid supercharger 20, an engine 30, and inboard control. The apparatus 40, the other controller 50, and the memory | storage part 60 are provided.
The power converter 10 includes a control device 100. However, the control apparatus 100 by 2nd embodiment is further provided with the motoring control part 103 with respect to the control apparatus 100 by 1st embodiment.
The motoring control unit 103 outputs motoring power (rotation maintaining power) to the motor generator 203 to perform motoring control.

Moreover, FIG. 7 is a figure which shows an example of the processing flow of the ship system 1 provided with the control apparatus 100 by 2nd embodiment.
Next, the processing flow (step S9, step S1-step S8) of the ship system 1 provided with the control apparatus 100 by 2nd embodiment is demonstrated using FIG. 6 and FIG.
The processing flow of the ship system 1 according to the second embodiment is a processing flow when the motoring control unit 103 performs motoring control by outputting motoring power to the motor generator 203. Therefore, the operation when the hybrid supercharger 20 is activated and the engine 30 is stopped will be described. However, the process of step S9 and step S10 different from the process flow of the ship system 1 by 1st embodiment is demonstrated here. In the hybrid supercharger 20 and the engine 30, various physical quantities, for example, pressure, flow rate, temperature, vibration, stress, operation time, rotation speed, electric power, etc. are measured using sensors, measuring instruments, and the like. .

The engine 30 is stopped and no exhaust gas is exhausted from the engine 30 to the turbine 201 of the hybrid supercharger 20. In this state, the motoring control unit 103 outputs motoring power to the motor generator 203 to perform motoring control (step S9). In addition, motoring control is control which operates the hybrid supercharger 20 independently by stopping the engine 30 and supplying electric power to the motor generator 203.
In this state, the supercharger state quantity acquisition unit 101 acquires measurement values of various physical quantities in each of the turbine 201, the compressor 202, and the motor generator 203 included in the hybrid supercharger 20 and the respective bearings (step S1). ).
The measured values of various physical quantities acquired by the supercharger state quantity acquiring unit 101 in step S1 are measured values of physical quantities based on the motoring power itself output to the motor generator 203 by the motoring control unit 103. For this reason, the measured values of various physical quantities acquired by the supercharger state quantity acquisition unit 101 do not include the influence of the engine 30 and indicate the characteristics of the hybrid supercharger 20 itself.

  Steps S2 to S4 are the same as the processing flow of the ship system 1 according to the first embodiment, and then the diagnosis unit 102 determines whether or not the remaining life of each component of each device is sufficient. (Step S10). In this step S10, the diagnosis unit 102 determines whether or not the remaining life of each component of each device is sufficient, in addition to the processing in step S5 of the processing flow of the ship system 1 according to the first embodiment, It is a process shown in FIG.

The past performance of the representative operating point, which is a typical value of the compressor map, is recorded in advance in the storage unit 60 as a compressor map data table.

  The diagnosis unit 102 receives the measured values of the compressor flow rate and the compressor pressure ratio acquired from the compressor 202 by the supercharger state quantity acquisition unit 101. The diagnosis unit 102 receives the measured value of the motor rig power input from the motoring control unit 103 acquired by the supercharger state quantity acquisition unit 101 from the motor generator 203. Further, the diagnosis unit 102 reads out the compressor map data table from the storage unit 60. Then, the diagnosis unit 102 specifies a representative operating point equivalent to the measured value of the compressor flow rate and the compressor pressure ratio received from the supercharger state quantity acquisition unit 101 in the compressor map data table read from the storage unit 60. Then, the diagnosis unit 102 compares the average value of past motoring power as a representative operating point to be identified with the measured value of the motoring power received from the supercharger state quantity acquisition unit 101, and determines a predetermined value. Whether or not the remaining life of each component of each device is sufficient is determined based on whether or not it is within the range.

  For example, it is assumed that the average value of past motoring power is 100 kilowatts and the measured value of motoring power received from the supercharger state quantity acquisition unit 101 is 101 kilowatts. In this case, the diagnosis unit 102 determines that the measured value of the motoring power received from the supercharger state quantity acquisition unit 101 has increased by 1% compared to the average value of past motoring power results, for example, a predetermined range Is equal to plus or minus 3 percent of the average value of past motoring power, it is determined that the hybrid turbocharger 20 is normal, that is, the remaining life of each component of each device is sufficient (step S10, NO), the supercharger state quantity acquisition unit 101 returns to the process of step S1 in which the measured values of various physical quantities in each of the turbine 201, the compressor 202, and the motor generator 203 and their respective bearings are acquired.

  Further, for example, it is assumed that the average value of past motoring power is 100 kilowatts and the measured value of motoring power received from the supercharger state quantity acquisition unit 101 is 110 kilowatts. In this case, the diagnosis unit 102 determines that the measured value of the motoring power received from the supercharger state quantity acquisition unit 101 has increased by 10% compared to the average value of past motoring power results, for example, a predetermined range Is plus or minus 3% of the average value of the past motoring power results, it is determined that the hybrid turbocharger 20 has failed, that is, the remaining life of each component of each device is not sufficient ( (Step S10, YES), the information regarding the component determined to have an insufficient remaining life and the device using the component is transmitted to the inboard control device 40 (step S6).
